The Spark is very much sweating glass.
If you are sweating, the glass should start with the windshield-it is necessary to include the stove on the heating. The main thing is to take your time and wait for the windshield. The glass is also supposed to be sweating. Like frostbite.
As an option, especially in winter time, you can warm the passenger compartment and wipe the glass from the inside with a towel or a towel. This procedure won't let them sweat again.
It is possible to include air conditioning with warm air-the recycling of air in the salon will also help glass to sweat.
